Rimac All Wheel Torque Vectoring is a unique system that creates a new driving experience by utilising the advantages of independent wheel drive of the Concept_One’s four-motor powertrain system. The system provides unseen flexibility and grip by controlling each wheel individually one hundred times per second. Drivers can choose between various modes and settings to perfectly match their preferences, skills and the given situation.
POWERTRAIN ARCHITECTURE
Electric motors offer numerous advantages compared to combustion engines. The Concept_One was designed from the ground-up to utilise those advantages and create a whole new breed – the supercar of the 21st century.
Rimac Automobili’s unique powertrain is divided into four sub-systems. Each system consists of a separate electric powertrain with an independent inverter, motor and gearbox for each wheel of the car. This engineering masterpiece enables us to control each wheel independently, hundreds of times each second, in both directions, delivering an unforgettable driving experience.
MOTORS & GEARBOXES
We have developed the world’s highest power density motor system to power each of the Concept_One’s four wheels individually. Instant response, more than 90% efficiency, full torque at zero speed, wide power-band and limitless lifetime are some of the advantages around which the Concept_One was designed from the ground-up.
Each of the four Concept_One’s motors is coupled to a proprietary gearbox system. While the front motors feature single-speed gearboxes, the rear motors carry something truly unique – a two-speed double-clutch gearbox on each side.
BATTERY SYSTEM
The Concept_One’s battery pack is designed to deliver 1MW of power during acceleration and to absorb 400 kW during braking. A unique liquid thermal management and low-resistance conducting system had to be developed in order to master this challenge. The result is a highly advanced high-performance battery pack that is designed for demanding track-use, high power delivery and safety.
